Abstract

621,310. Bushings. PHILIPS LAMPS, Ltd. Feb. 17, 1947, No. 4531. Convention date, March 14, 1944. [Class 36] An insulated lead-through device comprises an insulating body 3 through which the leadthrough conductor 1 passes, said body having a non-circular collar 5 and means, such as threads 7 for securing the device by a nut 9 into an aperture in the wall. The shaping of the collar 5 is such that when two or more lead-through devices are secured adjacent one another, they lock each other against rotation. A raised portion 11 is provided to increase the leakage path.
